@BAS-Viet-Nam Okay, thank you for the hint. Worked on many sites with these 2 functions without any problems. So I will try it with "Wait while element exists" on this specific site.
Hopefully I don't get in an endless waiting-loop ;)
@allister Hi, this is bug, it happens only if update column of int type. It was fixed, new version will be available in Thursday(8 November), if it is urgent for you, I can make a separate build.
